Industries we cover

Commercial solar funding by sector — where each grant route fits.

Different sectors fit different funding routes. Manufacturers fit IETF Phase 3. Schools and the NHS fit Salix PSDS Phase 4. Farms and rural businesses fit REPF. Logistics and retail fit PPAs. Hotels and offices typically fit the Annual Investment Allowance alone. Pick your sector below for the funding stack that actually applies — eligibility rules, project sizing, and the constraints we see most often.

Funding by asset class

The allowance depends on the asset, and most pages on this topic get it the wrong way round. Solar PV is special-rate expenditure (HMRC Capital Allowances Manual CA22335), so the 100% year-one route is the Annual Investment Allowance — Full Expensing is a main-rate measure and does not reach it. Battery storage, EV charging and heat pumps are main-rate plant, so Full Expensing genuinely does apply to those.

Find out which 2026 schemes your site actually qualifies for

What you get, within one working day
  • 1. A short written funding note naming every scheme your site qualifies for in 2026 — and the ones it does not.
  • 2. Indicative system size and a capex band for your roof.
  • 3. Year-one tax treatment per asset in £ — solar is special-rate expenditure, so the route is the Annual Investment Allowance; battery storage and heat pumps are main-rate plant, where Full Expensing does apply. Most pages get this the wrong way round.
  • 4. Projected SEG export revenue at current rates.
  • 5. Any red-flag eligibility or DNO issues we can see up front.

Covers solar PV, battery storage, EV charging and commercial heat pumps — separately or as one bundled project. If your project is a heat pump or a battery rather than a roof, say so in the message box and the note is written against that asset instead.

What we will not do
  • · We do not pass your details to multiple installers.
  • · We do not run a lead auction, and we never ask for your phone number.
  • · No marketing lists, no unsolicited calls.
  • · We are an independent funding consultancy — not an installer, and we take no installer commission.

Five questions. They are the eligibility test itself — scheme eligibility in 2026 turns on sector, tenure, site size and spend, so we cannot shortlist anything without them.

We reply from funding@commercialsolargrants.co.uk. No phone number required, ever.
